[. . . ] When shut they improve aerodynamics, shorten the engine's warm-up time and so reduce fuel consumption. Tyres with reduced rolling-resistance While driving, tyres are constantly changing shape. Tyres with reduced rolling-resistance have an improved design and use special materials for their road treads and side walls, thus reducing deformation. Brake Energy Regeneration To supply a battery with electrical energy, the generator (alternator) is permanently driven using engine power, which demands additional fuel consumption. Brake Energy Regeneration means the generator usually only generates electricity when the driver either takes the foot off the accelerator or brakes ­ previously unused kinetic energy is transformed in coasting mode into electrical energy before being fed into the battery. In this way, electricity is generated while coasting, without consuming fuel. Some BMW EfficientDynamics features are dependent on the car's equipment and are not available for all model variants.

[. . . ] One example is careful material selection designed to preserve resources and to ensure efficient recycling compatible with the environment. Each BMW is designed and built for simple and economic recycling after its long-running life. Since 1994, we have been collecting the know-how required for this purpose at the unique BMW Recycling and Dismantling Centre (RDC) near Munich. At the same time, the BMW Group is establishing a complete network of vehicle recycling facilities within Europe, focusing in the process on the high standards of quality and environmental care that BMW is renowned for.
